Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Abstract: A gel-forming composition comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, aldehyde operable for cross-linking with the first substance, and water. The gel-forming composition is useful for filling voids in porous substances and for retarding the flow of fluids in subterranean formations. For example, a method is provided for retarding the flow of fluids in high permeability channels in an oil reservoir. Such method is particularly useful in waterflood operations to increase the sweep efficiency of the oil recovery process. Since these gels have very good stability at elevated temperature they can be used in reservoirs having an average in situ temperature of 80<o>C or higher.
